A novel bionic algorithm inspired by plant root foraging behaviors

- A new bionic algorithm is proposed based on the incentive mechanism of plant root branching, regrowing and tropisms.
- A new plant root foraging strategy simulates the plant root tropism mechanism and sets up the dynamics mechanism of root growing rapidly towards the global optima.
- The auxin concentration is set up to determine how to select new growing points and branching number of roots.
- The mainroot regrowing and the lateral-roots regrowing operators can make appropriate balances between exploration and exploitation.
